York S1-022-08919-700 1/2″ x 5/8″ Sweat 8-Ton R22 Externally Equalized TXV

Description

Overview

The York S1-022-08919-700 is a precision-engineered Thermal Expansion Valve (TXV) designed for reliable refrigerant metering in commercial HVAC and refrigeration systems. Built to York’s exacting OEM standards, this straight-body TXV delivers consistent superheat control and efficient system performance in R22 applications rated up to 8 tons of capacity.

Key Features

• Refrigerant: R22 compatible
• Capacity: 8 Ton
• Inlet connection: 1/2″ sweat (ODF)
• Outlet connection: 5/8″ sweat (ODF)
• Body style: Straight body configuration
• Capillary tube length: 30″
• Equalization type: 1/4″ externally equalized for accurate pressure sensing in longer evaporator circuits

External Equalization Advantage

The 1/4″ external equalizer port connects downstream of the evaporator outlet, allowing the valve to sense true evaporator outlet pressure independently of the inlet pressure drop. This design is essential for multi-circuit evaporators and longer coil runs where significant pressure drop across the evaporator would otherwise cause hunting or under-feeding, ensuring stable superheat control and maximum system efficiency.

Applications

• York OEM replacement in commercial air conditioning systems
• R22 evaporator circuits up to 8-ton capacity
• Systems with multi-pass or longer evaporator coils requiring external equalization
• Direct-expansion (DX) cooling applications
